Bosch Alternator 12V 80A 0124315015

This Bosch alternator is a new 12V unit rated at 80A, supplied as part number 0124315015. It is listed as an alternator type excl. vacuum pump, with an internal regulator and a 6 groove multi-belt pulley, so the electrical and pulley setup needs to match the vehicle application before purchase.

Mounting dimensions are specific: inside mounting legs 45mm, mount centre to centre 165mm, pivot hole diameter 11 / M10, and adjusting hole diameter M8 x 1.25. Those measurements are the key checks for confirming the alternator will line up correctly with the existing brackets and belt drive.

The unit is described as a Bosch alternator, new, with a one year warranty. It is suited to Bosch applications and is intended as a replacement rotating electrical component where the original unit uses the same voltage, amperage, mounting style, and pulley configuration.

Application and Buying Notes

When matching an alternator, the most reliable checks are the part number, mounting dimensions, pulley groove count, and regulator type. For this unit, the critical identifiers are Bosch 0124315015, 12V, 80A, internal regulator, and a 6 groove multi-belt pulley with 57mm outside diameter.

The mounting pattern matters just as much as the electrical rating. This alternator uses twin leg mounting, 45mm inside mounting legs, 165mm centre to centre measurement, an 11 / M10 pivot hole, and an M8 x 1.25 adjusting hole. If any of those points differ from the original unit, it may not align correctly.

Because the alternator is listed as excl. vacuum pump, it should only be considered where the vehicle originally used that style. The note about recommended additional repairs also points to checking the V-belt or V-ribbed belt at the same time, since belt condition can affect charging performance and belt life.

If you are comparing against a removed unit, match the pulley section, regulator style, and the physical layout of the brackets before finalising the order. These are the practical checks that save time when fitting electrical components and reduce the risk of needing a second purchase.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 0124315015 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
